According to the previous experience, the new iPhone launched at Sep.12th should be called “iPhone 7s”, but it came to us with a name “iPhone 8”. When we saw iPhone 8 at first glance, it looks just like the iPhone 7. Here we will compare the iPhone 8 LCD screen with iPhone 7 and test whether the screens can exchange.

As iPhone 8 and iPhone 7 have the same size display, the LCD screen sizes are almost the same.

So we can’t find the differences from the front but there are some small differences on the back. Refer to the picture, the buckle on the top of iPhone 7 is plastic, on the bottom is metal while the iPhone 8 is just the opposite.
